Irfan Pathan produced a devastating spell of fast bowling to capture nine wickets including a hat-trick as India demolished Bangladesh by an emphatic 189-run victory in a league match of the Asian Under-19 tournament in Lahore today. After India were all out for 223 in 48.4 overs, the Baroda speedster virtually ran through the Bangladeshi innings returning with dream figures of 9/16 to give India their second successive victory in the tournament.
